Raiders make some moves to bolster depth

The Raiders signed cornerback Chance Casey, safety Shelton Johnson and linebacker Marshall McFadden to the active roster from the practice squad Saturday.

Those moves were necessary as the Raiders placed linebacker Kaluka Maiava and safety Usama Young on Reserve/Injured and waived defensive lineman Brian Sanford.

Young, who has a neck injury, played in 12 games and had 27 tackles (19 solo), 2.5 sacks (leading the secondary), one interception and two passes defensed. Maiava, who has a ribs injury, appeared in nine games and had 25 tackles (nine solo).
